Sound but no image when playing Apple TV - M1Pro
 

Hi,

I have a 14in M1Pro.
Using dock Kensington SC4750D
connected 2 Dell P2421DC
Everything was fine, except playing certain things:
Apple TV
And recently Disney+

Same issue: I can hear sounds and subtitles, but no image, just black.
All others are fine, youtube on chrome / safari, etc.

If I use USB-C to connect, just one screen, everything is fine too.
Not sure if some bug??

This issue is related to how macOS handles HDCP content through hardware acceleration, not a DisplayLink issue. Some browsers will be able to display content with hardware acceleration disabled, but the Apple TV app has no mechanism to disable that.
